yeah, i realize that it is going to be a litttle tough, but hey, isnt that part of the fun of doing it yourself. like i mentioned before, i COULD just buy an invertor, but this has become more of a personal challenge to myself. plus, the old psx that i have is just sitting around now, and i think i would learn a lot if i could make this work.
buying a ps1, with the car adapter and screen would cost over $200, making a 12v power supply will cost maybe $50, plus i already have an extra screen laying around, so i might as well try. oh, and im not about to trash my ps2 if something goes wrong with the power supply... i will keep you all informed as i make some progress.
